| ABSTRACT Housefly, Musca domestica, has a complicated immune system. However, its underlying operating mechanism remains elusive. Candida albicans is a major pathogen affecting humans by causing deep infection fungous disease, but it is non-symbiotic in houseflies. To investigate the C. albicans infection process in housefly, the changes in morphological and histological and expression patterns of antimicrobial peptide were monitored to indicate the insect's response to fungal infection. The results showed that scattered brown spots were comprising melanized encapsulation and encapsulated fungal cells were initially observed at the inner side of larvae's body wall 3 h post-infection (PI). Between 6 and 36 h PI, the whole body of larvae was densely covered... |

| ABSTRACT During the present study, the host-parasite relationship between mosquitoes and parasitic mites was investigated. The 8954 individuals of male and female mosquitoes belonging to 26 genera: seven each of Aedes and Culex, six of Anopheles and one each of Toxorhynchites, Coquillettidia and Uranotaenia were collected from 200 sites. The male and female mosquitoes were collected from the State of Uttar Pradesh, located at 26.8500° N, 80.9100° E in North India by deploying Carbon dioxide-baited and gravid traps. The intensity of mite's infection, type and number of mites attached to mosquitoes, mite's preference for body parts and host sexes were the parameters used to determine host-parasite relationship. Eight species of mites: Arrenurus acuminatus,... |

| Depuis 1991, d'importantes mortalités sont observées chez des lots de larves et de naissain d'huître creuse, Crassostrea gigas, mais également sur des lots de larves d'autres espèces de bivalve telles que, l'huître plate, Ostrea edulis, les palourdes, Ruditapes decussatus et Ruditapes philippinarum. Ces épizooties se produisent plus généralement à fortes températures en écloserie-nurserie et en période estivale dans le milieu naturel. Les techniques de détection utilisées jusqu'alors pour rechercher ces infections virales, histologie et microscopie électronique à transmission, paraissent assez inadaptées, tant du fait de leur sensibilité, du temps qu'elles nécessitent et de leur coût. Aussi, le laboratoire IFREMER de Ronce les Bains (Charente-Maritime) a... |

| The pathogenic strain V. splendidus 10/068 1T1 has previously been reported for its virulence to the blue mussel and for its capacity to alter immune responses. In this study, we expanded the knowledge on hemocyte-pathogen interactions by using in vitro and in vivo assays. V. splendidus 10/068 1T1 severely inhibited cell adhesion and acidic vacuole formation unlike the innocuous phylogenetically related V. splendidus 12/056 M24T1 which had no effect on these cell functions. Furthermore, the virulent bacteria decreased hemocyte viability (59% of viability after 24 h). Infection dynamics were explored by using a model based on water tank cohabitation with septic mussels infected by GFP-tagged V. splendidus 10/068 1T1. Experimental infections were... |

| Infection continues to be a major cause of morbidity and mortality worldwide. Nuclear medicine has an important role in aiding the diagnosis of particularly deep-seated infections such as abscesses, osteomyelitis, septic arthritis, endocarditis, and infections of prosthetic devices. Established techniques such as radiolabelled leucocytes are sensitive and specific for inflammation but do not distinguish between infective and non-infective inflammation. The challenge for Nuclear medicine in infection imaging in the 21st century is to build on the recent trend towards the development of more infection specific radiopharmaceuticals, such as radiolabelled anti-infectives (e.g. 99mTc- ciprofloxacin). In addition to aiding early diagnosis of infection, through... |

| Envenomation caused by snakes of the Bothrops genus produces a lesion in the bite site and can result in extensive necrosis. The dead tissue can be secondarily infected by bacteria that come from the snake, and the bacteria can be inoculated at the moment of the bite. The bacteria that most commonly cause infection are the enterobacteria, mainly Morganella morganii, Proteus rettgeri, Enterobacter sp., and Escherichia coli. Group D streptococci including here Enterococcus sp. and the Bacteroides sp. are also involved. Based on a study of the sensibility of these bacteria, it has been suggested that this infection must be treated with chloramphenicol, as a sole antimicrobial agent, or with the combinations of benzylpenicillin or ampicillin with... |

| The intestinal microbiota consists of a qualitatively and quantitatively diverse range of microorganisms dynamically interacting with the host. It is remarkably stable with regard to the presence of microorganisms and their roles which, however, can be altered due to pathological conditions, diet composition, gastrointestinal disturbances and/or drug ingestion. The present review aimed at contributing to the discussion about changes in the intestinal microbiota due to HIV-1 infection, focusing on the triad infection-microbiota-nutrition as factors that promote intestinal bacterial imbalance. Intestinal microbiota alterations can be due to the HIV-1 infection as a primary factor or the pharmacotherapy employed, or they can be one of the consequences of the... |

| The objective of this study was to isolate and characterize Streptococcus spp. in Nile tilapias (Oreochromis niloticus) reared in net-pens and earth nurseries. Eight intensive tilapia-rearing farms were investigated in north Paraná, Brazil from April 1st 2001 to April 30th 2002. The fish were reared in a system of hapas nets on four farms and in earth nurseries on other four farms. A total of 370 samples were analyzed of material collected from 120 fish (brain, liver, kidney, skin scrapes, ascites liquid and eye) that were sown on BHI agar (Brain Heart Infusion) supplemented with 1% yeast extract and sheep blood. Streptococcus spp. was isolated in 36 of the samples (18 brain, eight liver, eight kidney and two ascites liquid) from 25 fish. Streptococci were... |

| The relationship among the phenotypes resistance to infection, virus replication in the brain and isotype production was investigated in genetically modified High (H) or Low (L) antibody responder mouse lines. Although they express the same innate susceptibility to rabies infection, these lines differ as to different viral replication rates in the central nervous system and L mice showed a higher permissible state. After intramuscular infection with the Pasteur rabies strain (PV), the H-L interline differences on the earlier stage of virus replication were 1000 and 80 folds on days 5 and 6, respectively. The isotype profile in sera of the experimentally infected mice reflected an interline difference of 25 folds for IgG2a throughout the infection period,... |

| Nucleic acid amplification testing (NAT) was recently recommended by Brazilian legislation and has been implemented at some blood banks in the city of São Paulo, Brazil, in an attempt to reduce blood-born transmission of human immunodeficiency virus (HIV) and hepatitis C virus. OBJECTIVE: Manual magnetic particle-based extraction methods for HIV and HCV viral nucleic acids were evaluated in combination with detection by reverse transcriptase - polymerase chain reaction (RT-PCR) one-step. METHODS: Blood donor samples were collected from January 2010 to September 2010, and minipools of them were submitted to testing. ELISA was used for the analysis of anti-HCV/HIV antibodies. Detection and amplification of viral RNA was performed using real-time PCR.... |

| ABSTRACT Austrodiplostomum compactum is a digenetic trematode whith metacercariae that occur in the eyes of a wide variety of fish species. In Brazil, A. compactum metacercariae have been reported in many fish species, but there are only a few studies in the Amazon region. Due to the lack of information in the Amazon, the aim of this study was to report the occurrence of A. compactum metacercariae in the eyes of 15 specimens of Plagioscion squamosissimus from the Lake Catalão, in Amazonas, Brazil. Fishes were collected using gill nets placed randomly in the lake, euthanized in a field laboratory, and had their eyes dissected and examined under a stereomicroscope. A total of 801 metacercariae were registered infecting the eyes of the hosts with a parasitic... |
